HI people,

I'm tuning a server that is a long time abandoned, and this server is a little slow.
Now, in my postgresql.conf I have:
shared_buffers = 100Mb
mas_fsm_relations = 15000
mas_fsm_pages = 1600000
max_connections = 300

And I changin' to:
shared_buffers = 1000Mb
   (The server has 2 Gb of memory)
mas_fsm_relations = 15000
   (The Vacuum noticed me 608 relations)
mas_fsm_pages = 1600000
   (The Vacuum noticed me 500800 pages)
max_connections = 300
   (I did a "ps axf | grep postgres | wc -l" and the bash brings to me the number of 120 and all the people is not online at now)

My qustion is about shared_buffers, in postgresql.conf I have: min 128kB or max_connections*16kB  # (change requires restart)
So I did:
300 * (16Kb / 1024) = 4,69?
What this result means?

Thnks all,

Rafael Domiciano
